Please see RFC 7230, Section 5.4. The full URI would include scheme and the path, which are not included in the host header. Correct, i.e. Host = uri-host [ ":" port ] and if we follow the breadcrumbs to uri-host uri-host = <host, see [RFC3986], Section 3.2.2> where host = IP-literal / IPv4address / reg-name and of course it's IP-literal that we redefine in RFC6874 and the present draft. In the ideal world, RFC7230 should IMHO have cited RFC6874 as well as RFC3986. However, what I was getting at is that a browser that mangles the IP-literal by *removing* the ZoneID, as required by RFC6874, would be violating the behaviour described by RFC7230. Since we propose to delete that requirement anyway, the issue is moot for the present draft. Sorry about my lack of clarity.
